TRAP-NEST.

Application filed March 3, 1913. Serial No. 751,945

To all whom it may concern Be it known that LFREDERIOK J. CAnLsoN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements inTrap-Nests, of which the following is a specification.

My invention relates to trap nests and the object of this improvement is to provide an improved device of the character mentioned which will be simple in construction and eflicient in operation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

r The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which Fig. 3 is a vertical section taken on a line indicated by line 3-3 in Fig. 4, and Fig. 4

is a horizontal section similar to Fig. 2 but taken at the position indicated by line 4-4 in Fig. 3.

The preferred form of construction as i disclosed in the drawing comprises a frame made up of corner posts 3 a bottom casting 4 and upper casting or web 5. A conical shaped hood 6 rests on the top of web 5. An ear 7 is depended from the cast-ing 4 and a lever 8 pivoted therein, as at 9, a shiftable weight 10 is mounted on the lever 8 and adapted to be moved along the lever to accommodate the different weights of hens which will use the nest. The other end of Q the lever 8 is provided with a cup 11 which supports the nest.

vent other hens from entering the coop whileit is occupied. I 7

A tubular casing 14 is provided with an entrance opening 15 through which the hen enters and leaves the nest. The lowerportion of the tubular member 14 carries the nest 16 and said nest is provided with a Specification of Letters Patent.

perforation 17 in its central portion through which the egg is deposited. A chute 18 is carried on the under side of the nest 16 with its lower end closed by a swinging door 19. Said door 19 is adapted to remain in its closed position by gravity, and upon an egg 20 passing through the chute 18 and contacting it, said door will open to allow the egg to pass through at the proper time into a receptacle 21 under the device.

Across .thetop of the tubular member 14 isa bar 22 which carries an anger member 23 which engages a suitable slot in the web 5 to effect rotation of the tubular member 14 upon vertical movement thereof. The lower portion of the tubular member 14 is provided with a similar bar 24 which carriers a point 25 in its centralportion and said point25 rests in the cup 11 of lever 8 3 to support the nest.

Figure 1 is a vertical section of a device embodying my invention, Fig. 2 is a section 1 of the same taken on line 2-2 in Fig. 1.

p A stop 26 is carried on the lower edge of door 19 and is adapted to engage a stop 27 carried by the casting 4 to stop the rotation of the nest andits mounting. The stop 27 effectively locks the rotation of said nest memberuntil an egg is deposited in the nest 16 and passes through the chute 18 and engages the door 19 whereupon the door 19 yields substantially to the position indicated by the dot-ted lines 28 in Fig. 1 whereupon the stop 26 engages a member 29 .which prevents the'door 19 from opening until the nest member hasrotated far enough to permit the egg to be deposited in the receptacle 21 under the device.

1 electrical switch member 30 is carried by and insulated from the casting 4 on an insular, base member 31 and in a position to be engaged a contact member 32 carried on the tubular member 14 when said tubular 1 member is rotated to the position in which Flap doors 12 are pivoted to posts 3, as at 13, and adapted to be swung outwardly to allow a hen to leave the coop and to pre until such movement is arrested by the stop 26 engaging stop 27 whereupon the nest member remains in this position until either unlocked by an egg passing through passage 18 to move the stop 26 from engagement with the stop 27, or until the hen raises a door 12 and passes out of the device. When the nest member is in this position, the door opening 15, chute 18 and door 19 take the positions indicated by dotted lines 15, 18 and 19 respectively in Fig. 4.. If the hen has laid, the egg passes through chute 18 unlocks the device as already described and allows the nest member to rotate until it reaches the dotted line position indicated in Figs. 1 and 4:- In this latter condition door opening 15, chute 1S and door 19 are in the positions indicated by dotted lines 15", 18 and 19" in Fig. 4:. The contact member 32 of the electric switch engages the contact member 30 on casting 4 which action stops the rotation of the nest member. As soon as the hen raises the door 12 at the right hand of Fig. 1 and passes out through opening 15 the weight 10 causes the nest member to rotate in the opposite direction to its full line, or normal, position shown in Fig. 1 ready to be occupied again. The electric wires 38 leading from the contact member 30 and casting 1 are intended to be led to a place convenient to cause an alarm to notify the person in charge that the hen has laid so that a suitable marking may be placed on the egg to identify the egg. When it is desired to keep track of the eggs, a pen or coop, not shown, is provided on the side of the device next the right hand side of the figures so that a hen upon leaving the device must pass into such a coop. After the egg has been marked the hen may be released from the coop.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within thescope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1.
